6 INSTALLATION PROCEDURES Carpentry Procedures Case Pull-Up Locations The models have two pull-ups at each end of the case. Pull-ups A and B are located as shown and should be installed and tightened starting with A and finishing with B. See General-UL/NSF I&S Manual for line-up assembly instructions. Raceway Cover & Rear Base Close-off Installation Position raceway cover (1) over rear raceway opening and secure with screws in every hole. Rear Base and End Close-off Installation Kickplate, optional rear base and end closeoffs have spring clips on their back sides that secure to the pipe legs. NOTE Optional rear base close-offs do not require joint trim. 1. Before installing kickplates on a multiple case lineup, snap a joint trim (2) over the top and bottom of one end of each kickplate (3). 2. Lineup each kickplate (3) and/or optional rear base close-off (4) and push to secure the spring clips to the legs (5). 3. Slide joint trims (2) over the case-to-case joints. 4. Position end close-offs (6) over the end of the kickplate (3) and/or optional rear base close-off (4) and push until the spring clips secure to the legs (5). Trim & NSF Thermometer Installation The joint trim and mounting hardware are shipped loose. Trim includes rear top joint trim, card molding joint trim, rear duct joint trim, glass joint trim, color band joint trim, upper front cladding joint trim, lower front cladding joint trim, kickplate joint trim and horizontal end trim. Horizontal end trim covers gaps between the cases. The trim is glued onto the shipping cardboard. Apply trim with notch side towards front of case, after running beads of caulking on the edges of the cases. Sheet metal screws can be used for additional securing. Page 6 May, 2007

7 Installation & Service Manual Patch end trim is shipped factory installed. If field installation is required, be sure the patch end is pulled up enough to fit snuggly against the sealing tubing on the inside of the case. The patch end must seal tightly against the lift glass wiper to ensure proper operating temperatures. The NSF case thermometer and bracket assembly is shipped loose with the case. After removing the thermometer and bracket assembly from the shipping packaging, position bracket over left horizontal joint trim and case-to-case joint where the joint trim is notched out. Make sure the bracket is positioned to the front of the case, flush with the top and left inside edge of the bottom case end welds. Secure thermometer bracket to with two screws in the pre-drilled holes. Electrical Procedures Electrical Considerations CAUTION Make sure all electrical connections at components and terminal blocks are tight. This will prevent burning of electrical terminals and/or premature component failure. NOTE The raceway houses the electrical wiring and components for the case. Since the lower front cladding is shipped loose, the raceway has immediate access. Case Fan Circuit This circuit is to be supplied by an uninterrupted, protected 120V circuit. The case fan circuit is not cycled during defrost on any of these models. Defrost Information See General-UL/NSF I&S Manual for operational descriptions for Off Time defrost control. Defrost Control Chart Defrost Defrost Defrosts Duration Term. Type Per Day (Min) Temp. Off Time WIRING DIAGRAMS ELECTRICIAN NOTE - OVERCURRENT PROTECTION 120V circuits should be protected by 15 or 20 Amp devices per the requirements noted on the cabinet nameplate or the National Electrical Code, Canadian Electrical Code - Part 1, Section V defrost circuits employ No. 12 AWG field wire leads for field connections. On remote cases intended for end to end line-ups, bonding for ground may rely upon the pull-up bolts. The following wiring diagram on page 8 covers all the case electrical circuits.

Remove screws and front upper cladding from the case. 4. After cleaning, replace front upper cladding and remaining front components in the reverse order. Cleaning Instructions WARNING TYLER Refrigeration does not recommend the use of high pressure cleaning equipment on service style cases!! The sealing of front glass and end joints is critical in these cases and high pressure cleaners can penetrate and/or damage these seals. Damaged seals allow water leaks and/or air leaks that can cause poor case refrigeration. CAUTION When cleaning this case, try not to introduce water into the case faster than it can be carried away by the waste outlet. Liquid chlorine bleach is corrosive to metals. The use of bleach or products containing bleach will damage metal surfaces and void the case warranty. Sanitize the case with Quaternary Ammonium Solutions (ex: KAYQUAT II, J-512 Sanitizer, SANIQUAT 512, etc...) approved per 21CFR , followed by adequate draining and air drying. These solutions may be obtained from Kay Chemical Co., Johnson Wax Professional, Coastwide Laboratories, etc... Always use a soft cloth or sponge with mild detergent and water to clean the front glass. Never use abrasives or scouring pads to clean glass. They can scratch and/or damage the glass. See General (UL/NSF) I&S Manual for case cleaning instructions. May, 2007 Page 9

SERVICE INSTRUCTIONS See General-UL/NSF I&S Manual for fan blade & motor and color band & bumper replacement instructions. Connecting the Refrigeration Piping and Components WARNING Be sure to position a flame and heatresistent shield over the bottom of the case liner. Heat from brazing could damage the liner and/or cause personal injury or death from fire. 1. Remove screws and refrigeration piping cover from the left bottom of the case. 2. Position loose refrigeration piping and/or optional valves between the open lines in the bottom and upright of the case. NOTE Make sure all sensor and thermostat wires are clear of areas being heated. Mount all refrigeration lines off the floor to allow for cleaning access. 3. Apply flux to all joint ends. Starting at one end, thoroughly heat each new pipe joint and braze it together. Repeat this process until all new pipe joints have been brazed. 4. After piping has cooled, route and connect thermostat and sensor wires through openings in the bottom of the case. May, 2007 Page 11
